# strbit
--------

The purpose of this Lua module is to perform bitwise operations on the bytes of Lua strings, "in parallel". It's probably most useful when manipulating bitmaps represented as strings (e.g. for collision detection in games), but there may be other uses.

Supported bitwise operations are: `bshiftleft` (and shift right via negative parameter), `band`, `bor`, `bxor`, `bnot`.
